Chad Hansen

Python Full-Stack Engineer | FastAPI/Django, React/Next.js, PostgreSQL/Supabase, Docker, APIs

🚀 I help SaaS teams, operations-heavy businesses, facilities & field-service companies, and startups build reliable full-stack platforms using Python, FastAPI, React, PostgreSQL, and cloud-native DevOps practices.

I'm a Full-Stack Python Engineer with 6+ years of experience building production systems that businesses run their daily operations on — work order and ticketing platforms, dispatch and scheduling tools, client portals, admin dashboards, and API-driven backends that other services depend on.

A production system isn't just working code — it's uptime, data integrity, and change management done right. My job is to take a feature-complete codebase, whether I wrote it or inherited it, and turn it into something a business can depend on every day: correct state and SLA logic, safe deploys, tested backups, clear monitoring, and a codebase the next engineer can actually understand.

🐍 Backend & APIs: FastAPI, async SQLAlchemy, Pydantic, PostgreSQL, Alembic, Redis, background workers, webhook ingestion, REST & WebSocket APIs, role-based access control, multi-tenant architecture.

⚛️ Frontend & PWA: React, TypeScript, Vite, Tailwind CSS, installable PWAs, offline-capable apps, bilingual (EN/AR, RTL-ready) interfaces, dashboards, and portals for internal teams and external clients.

🛠️ Production & DevOps: Docker/Docker Compose, CI/CD with isolated test databases, TLS & secrets management, structured logging, monitoring, tested backup/restore drills, staged rollouts, and incident response.

What I focus on

✅ Reliability: safe deploy pipelines, health checks, retry/queue logic, and rollback plans so "it broke after my deploy" never happens.

✅ Data integrity: schema design, migrations, audit trails, and time-series data (TimescaleDB) that hold up under real business load.

✅ Domain logic: encoding real operational rules — approval flows, SLA/escalation clocks, compliance schedules, state machines — directly into the system, not bolted on afterward.

✅ Handover & takeover: reading unfamiliar codebases fast, writing the missing docs, and shipping small, reviewed changes instead of risky rewrites.

Why clients hire me

🔸 I take ownership of systems end-to-end — database, API, frontend, and the server they run on — instead of touching only "my part."

🔸 I read unfamiliar codebases quickly and can tell you, in plain language, what's solid and what's risky before I touch anything.

🔸 I treat backups, monitoring, and staging environments as part of the job, not optional extras.

🔸 I communicate clearly with founders, operations teams, and other engineers, and I keep a steady daily overlap with clients across different time zones.
